Description

Technical Field

[0001] This invention belongs to the field of laser cutting device technology, specifically a laser cutting device for steel structure plates. Background Technology

[0002] Steel structural panels are a core material widely used in steel structure engineering. They refer to flat components made of steel as the base material and processed into a flat shape through specific techniques. They are mainly used to bear structural loads or as part of the building envelope. During the production and processing of steel structural panels, laser cutting is often required to achieve specific dimensions to meet different usage requirements.

[0003] Patent CN220515749U discloses a laser cutting device for steel structure panels, including a frame, a sliding rail movably mounted on the surface of the frame, a movable seat movably mounted on the surface of the sliding rail, a cutting assembly movably mounted on the surface of the movable seat, and a support plate assembly fixedly connected to the top of the frame. This patent describes a process where, when the steel structure panel is placed on top of the frame, it is positioned inside a U-shaped plate. Starting the motor causes the motor's output to rotate a worm gear, which in turn rotates a worm wheel. The worm wheel then rotates a rotating plate, which in turn moves a lifting plate downwards. The lifting plate then moves the U-shaped plate downwards. When the U-shaped plate descends to a certain depth, it flattens the raised outer ends of the steel structure panel, providing a stable cutting advantage. The flattened raised ends of the steel structure panel facilitate normal laser cutting and improve the cutting effect.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] When laser-cutting steel structure panels, the panels need to be clamped and fixed before cutting. When there are many panels to be cut, in order to improve continuous cutting efficiency and save manpower, a robotic arm is used to pick up the panels to be cut one by one and place them in the panel clamping area for cutting. However, in some cases, the panels to be cut may be stacked disorderly in the same place after the previous process. This will result in inconsistent placement of multiple panels, making it difficult for the robotic arm to accurately pick up the panels according to the preset path. In addition, visual recognition is difficult and prone to errors, thus affecting the efficiency of continuous cutting of multiple panels. Summary of the Invention

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The laser cutting device for steel structure plates described in this invention utilizes a slotted conveyor plate feeding assembly. First, a gripper cylinder clamps the plate between two slotted plates. Then, the plate is fixed and cut. During the entire automatic feeding process, multiple plates that were originally stacked haphazardly are conveyed one by one to the end of the frame and kept vertical by the cooperation of the slotted plates and the conveyor belt. The gripper cylinder can then sequentially clamp the plates according to a preset path, reducing visual recognition difficulty and minimizing clamping errors, thus improving the efficiency of continuous cutting of multiple plates. Furthermore, by adjusting the distance between the upper surface of the conveyor belt and the bottom of the adjusting plate, making this distance equal to the side length of the plate, the plate can smoothly pass under the adjusting plate when the gripper cylinder clamps it. The plate above the clamped plate is blocked by the adjusting plate and will not move with the plate below due to friction, thus preventing the plate from falling onto the base and further ensuring the normal operation of the feeding process.

[0022] 2. The laser cutting device for steel structure panels described in this invention utilizes an anti-jamming booster assembly. When the panel is placed above the drive rollers, multiple drive rollers rotate synchronously, driving the panel laid flat on the drive rollers towards the drop plate through friction. After the panel falls into the drop plate, the drop plate rotates, tilting the panel onto the multiple drive rollers. This cycle is repeated multiple times, changing the orientation of the panel laid flat on the drive rollers until the panel slides into the gap. Furthermore, as the drive rollers rotate, the push plate also rotates. When the push plate is in contact with the bottom of the panel, it applies an upward oblique force to the panel, causing it to move towards the drop plate. By continuously applying an upward oblique force to the panel, it ensures that the panel slides smoothly into the drop plate, guaranteeing the normal tilting of the panel by the drop plate. Compared to the method of applying a lateral thrust to push all the panels laid flat on the drive rollers into the drop plate at once, this method avoids external forces on the panel entering the gap, preventing movement interference and damage to the panel due to compression.

[0045] Specifically, in existing technologies, when laser cutting steel structure panels, the panels need to be clamped and fixed before cutting. When there are many panels to be cut, in order to improve continuous cutting efficiency and save manpower, a robotic arm is used to sequentially clamp the panels to be cut and place them in the panel clamping area for cutting. However, in some cases, the panels to be cut may be stacked disorderly in the same place after the previous process. This results in inconsistent placement of multiple panels, making it difficult for the robotic arm to accurately clamp the panels according to the preset path. Furthermore, visual recognition is difficult and prone to errors, thus affecting the efficiency of continuous cutting of multiple panels.

[0046] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0047] Firstly, this solution is applied to steel structure panels of the same specifications and square on both sides. These panels often need to be laser-cut into two parts to meet different design and usage requirements. Based on the panel thickness, cylinder 25 drives the inclined slot plate 26 to rise and fall. As the inclined slot plate 26 rises and falls, it moves the guide column 38, causing multiple slotted plates 49 to slide simultaneously on the support plate 29. Due to the different angles of the multiple inclined slots, the multiple slotted plates 49 will change at equal intervals until the distance between two adjacent slotted plates 49 and two adjacent drive rollers 35 is equal to the panel thickness. Simultaneously, cylinder 24 drives the baffle 7 to move laterally, ensuring that the bottom edge of the baffle 7 is always aligned with the last drive roller 35. Then, the disorderly stacked boards are placed uniformly above the drive roller 35. Since only one board can pass through the gap created by two adjacent gap boards 49 and two adjacent drive rollers 35 at a time, the board will slide into the gap under the action of gravity and stick to the surface of the conveyor belt 27. At the same time, the conveyor belt 27 will drive the board to move towards the end of the frame 5 and be blocked by the stop block 46, so that it will not fall through the end of the conveyor belt 27. Since there are many gaps, the board also has multiple feeding channels, which avoids the situation of the board being fed from only one side and causing accumulation and blockage, and helps to improve feeding efficiency. Subsequently, the lead screw guide rail 30 drives the slider 2 32 to slide laterally on the lower end face of the guide rail plate 3 11, so that the vision sensor 33 alternately aligns with the inner side of different gaps. If there is a plate in the gap and the plate is blocked by the stop block 46, the cylinder 7 44 can be driven to slide laterally on the adjusting plate 43 under the action of the lead screw guide rail 42, so that the lowering rod 45 aligns with the corresponding stop block 46. Then, the cylinder 7 44 drives the lowering rod 45 to descend, so that the lowering rod 45 contacts the stop block 46. When the two surfaces come into contact at an angle, the stop block 46 will move laterally under the pressure of the lower pressure rod 45, and the spring 47 will be compressed, so that the stop block 46 no longer blocks the plate in the gap. The plate continues to move under the action of the conveyor belt 27 until the plate is at the clamping end of the gripper cylinder 34. Then the gripper cylinder 34 clamps the plate and pulls it out of the gap under the action of the lead screw guide rail 4. At the same time, the lower pressure rod 45 resets and uses the stop block 46 to block the subsequent plate. Then the motor 21 drives the gripper cylinder 34 to rotate 90 degrees to make the plate horizontal. Then the above adjustment is repeated to adjust the position of the plate being clamped and place the plate on the upper end of the two positioning plates 14. The cylinder 2 13 drives one side of the positioning plate 14 to move, so that the plate can be clamped with the cooperation of the two positioning plates 14. Then the gripper cylinder 34 releases the plate and drives the transverse plate 3 to slide to the right, so that the gripper cylinder 34 moves away from the plate. Then, by using the lead screw guide rail 22 and the motor 19 to drive the gear 20 to rotate, the position of the laser cutting head 16 in the x and y axis directions is adjusted, and the position of the laser cutting head 16 in the z axis direction is adjusted by the cylinder 3 18. Furthermore, the movement of the laser cutting head 16 does not interfere with the movement of the gripper cylinder 34.The laser cutting head 16 can be used to cut the sheet into two parts, and then the gripper cylinder 34 can clamp the sheet along the cutting seam. A collection box can be placed on the base 1, and the gripper cylinder 34 can place the cut sheet into the collection box for collection. Then the above operation is repeated. First, the gripper cylinder 34 clamps the sheet between the two clamping plates 49, and then the sheet is fixed and cut. In the entire automatic feeding process, the multiple sheets that were originally stacked in a disordered manner will be transported one by one to the end of the frame 5 with the cooperation of the clamping plates 49 and the conveyor belt 27 and kept in a vertical position. Then the gripper cylinder 34 can clamp the sheet sequentially according to the preset path. The visual recognition difficulty is low and the clamping error is not likely to occur, which helps to improve the efficiency of continuous cutting of multiple sheets.

[0048] Furthermore, in the above solution, when the gripper cylinder 34 removes the plate from the gap, if two plates overlap, the gripped plate may pull the plate above it out of the gap due to friction, causing the plate to fall onto the base 1, thus affecting the normal operation of the gripping work. Therefore, to avoid this situation, cylinder six 40 drives the adjusting plate 43 to rise and fall, adjusting the distance between the upper surface of the conveyor belt 27 and the bottom of the adjusting plate 43, making this distance equal to the side length of the plate. When the gripper cylinder 34 grips the plate, the plate can pass smoothly under the adjusting plate 43, and the plate above the gripped plate will be blocked by the adjusting plate 43, preventing it from moving with the plate below due to friction, thus avoiding the plate falling onto the base 1 and further ensuring the normal operation of the feeding work.

[0049] In this embodiment, as Figures 6-9 As shown, it also includes an anti-jamming booster component;

[0050] The anti-jamming booster assembly includes a housing 28 fixedly connected to one side of the slotted plate 49, a worm gear 39 fixedly connected to one end of the transmission roller 35, the worm gear 39 being rotatably mounted on the slotted plate 49 and the housing 28, and worms 37 being rotatably mounted at both ends of the inner cavity of the housing 28, the worms 37 meshing with the worm gear 39, and two adjacent worms 37 being inserted and slidably connected through keyways, and a motor 36 being fixedly connected to one side of the outer wall of one side of the housing 28, the output end of the motor 36 being fixedly connected to one end of the worm 37.

[0051] A drop plate 6 is rotatably mounted on one side of the frame 5, and a motor 41 is fixedly connected to one side of the upper end of the frame 5. The output end of the motor 41 is fixedly connected to one side of the drop plate 6.

[0052] A push plate 12 is inserted into and slidably connected to one side of the transmission roller 35, and an electric push rod 48 is fixedly connected to one side of the inner wall of the transmission roller 35. The piston end of the electric push rod 48 is fixedly connected to one side of the push plate 12.

[0053] Specifically, in the above embodiments, although the automatic feeding of the board can be achieved by letting the board slide down into the gap between two adjacent gap boards 49, when the board falls above the gap board 49, some of the board will lie flat on the transmission roller 35, which will cause some of the board to fail to slide down into the gap normally, thus affecting the normal feeding of the board.

[0054] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0055] When the board is placed above the drive roller 35, it is within the enclosure formed by the first baffle 7, the drop plate 6, and the two second baffles 23. When the distance between two adjacent drop plates 6 changes, the two adjacent worms 37 will also slide relative to each other. The worm 37 and the worm wheel 39 always remain engaged. Then, the motor 36 drives one side of the worm 37 to rotate, so that multiple worms 37 and worm wheels 39 rotate simultaneously. As a result, multiple drive rollers 35 rotate synchronously. Through friction, the board laid flat on the drive roller 35 is driven to move into the drop plate 6. After the board falls into the drop plate 6, the motor 41 drives the drop plate 6 to rotate. The board in the drop plate 6 will be tilted onto multiple drive rollers 35. This cycle is repeated many times, so that the orientation of the board laid flat on the drive roller 35 can be changed under the action of external force until the board can slide into the gap, thus further ensuring that the board can slide smoothly into the gap.

[0056] However, in some cases, the surface of the board to be cut is relatively smooth. When the board comes into contact with the drive roller 35, it is difficult for the board to move laterally under the action of friction. As a result, the board laid flat on the drive roller 35 cannot move normally into the drop plate 6, which also affects the normal feeding of the board. Therefore, to avoid this situation, the push plate 12 also rotates during the rotation of the transmission roller 35. When the push plate 12 is in contact with the bottom of the board, the electric push rod 48 drives the push plate 12 to move, applying an upward oblique pushing force to the board, causing the board to move into the drop plate 6. After the push plate 12 completes one pushing action, it will retract into the inner cavity of the transmission roller 35, so as not to interfere with the board sliding into the gap. Thus, by continuously applying an upward oblique pushing force to the board, the board can slide smoothly into the drop plate 6, ensuring the normal tilting of the board by the drop plate 6. Moreover, compared with the method of applying a lateral pushing force to push all the boards laid flat on the transmission roller 35 into the drop plate 6 at once, this method will not cause the board entering the gap to be subjected to external force, avoiding motion interference and damage to the board due to compression.

[0057] Working principle: Based on the thickness of the sheet material, cylinder 25 drives the inclined groove plate 26 to rise and fall. When the inclined groove plate 26 rises and falls, it drives the guide column 38 to move, so that multiple clamping plates 49 slide on the support plate 29 at the same time. Since the angles of the multiple inclined grooves are different, the multiple clamping plates 49 will produce equidistant changes until the distance between two adjacent clamping plates 49 and two adjacent transmission rollers 35 is equal to the thickness of the sheet material. At the same time, cylinder 24 drives the baffle 7 to move laterally, so that the bottom edge of the baffle 7 is always aligned with the last transmission roller 35. Then, the disorderly stacked boards are placed uniformly above the drive roller 35. Since only one board can pass through the gap created by two adjacent gap boards 49 and two adjacent drive rollers 35 at a time, the board will slide into the gap under the action of gravity and stick to the surface of the conveyor belt 27. At the same time, the conveyor belt 27 will drive the board to move towards the end of the frame 5 and be blocked by the stop block 46, so that it will not fall through the end of the conveyor belt 27. Since there are many gaps, the board also has multiple feeding channels, which avoids the situation of the board being fed from only one side and causing accumulation and blockage, and helps to improve feeding efficiency. Subsequently, the lead screw guide rail 30 drives the slider 2 32 to slide laterally on the lower end face of the guide rail plate 3 11, so that the vision sensor 33 alternately aligns with the inner side of different gaps. If there is a plate in the gap and the plate is blocked by the stop block 46, the cylinder 7 44 can be driven to slide laterally on the adjusting plate 43 under the action of the lead screw guide rail 42, so that the lowering rod 45 aligns with the corresponding stop block 46. Then, the cylinder 7 44 drives the lowering rod 45 to descend, so that the lowering rod 45 contacts the stop block 46. When the two surfaces come into contact at an angle, the stop block 46 will move laterally under the pressure of the lower pressure rod 45, and the spring 47 will be compressed, so that the stop block 46 no longer blocks the plate in the gap. The plate continues to move under the action of the conveyor belt 27 until the plate is at the clamping end of the gripper cylinder 34. Then the gripper cylinder 34 clamps the plate and pulls it out of the gap under the action of the lead screw guide rail 4. At the same time, the lower pressure rod 45 resets and uses the stop block 46 to block the subsequent plate. Then the motor 21 drives the gripper cylinder 34 to rotate 90 degrees to make the plate horizontal. Then the above adjustment is repeated to adjust the position of the plate being clamped and place the plate on the upper end of the two positioning plates 14. The cylinder 2 13 drives one side of the positioning plate 14 to move, so that the plate can be clamped with the cooperation of the two positioning plates 14. Then the gripper cylinder 34 releases the plate and drives the transverse plate 3 to slide to the right, so that the gripper cylinder 34 moves away from the plate. Then, by using the lead screw guide rail 22 and the motor 19 to drive the gear 20 to rotate, the position of the laser cutting head 16 in the x and y axis directions is adjusted, and the position of the laser cutting head 16 in the z axis direction is adjusted by the cylinder 3 18. Furthermore, the movement of the laser cutting head 16 does not interfere with the movement of the gripper cylinder 34.The laser cutting head 16 can be used to cut the sheet into two parts, and then the gripper cylinder 34 clamps the sheet along the cutting seam. A collection box can be placed on the base 1, and the gripper cylinder 34 collects the cut sheet in the collection box. This process is repeated, with the gripper cylinder 34 first clamping the sheet between two clamping plates 49, then fixing and cutting the sheet. During the automatic feeding process, the previously disordered sheets are transported one by one to the end of the frame 5 and kept vertical by the cooperation of the clamping plates 49 and the conveyor belt 27. The gripper cylinder 34 can then clamp the sheets sequentially along a preset path, reducing visual recognition difficulty and minimizing clamping errors, thus improving the efficiency of continuous cutting of multiple sheets. However, in the above solution, if two sheets overlap when the gripper cylinder 34 removes the sheet from the clamp, the clamped sheet may pull the sheet above it out of the clamp due to friction, causing it to fall onto the base 1 and affecting the normal operation of the clamping process. Therefore, to avoid this situation, cylinder 6 40 is used to drive the adjusting plate 43 to rise and fall, adjusting the distance between the upper surface of the conveyor belt 27 and the bottom of the adjusting plate 43, and making this distance equal to the side length of the plate. When the gripper cylinder 34 grips the plate, the plate can pass smoothly under the adjusting plate 43. Furthermore, the plate above the gripped plate will be blocked by the adjusting plate 43 and will not move with the plate below due to friction, thus preventing the plate from falling onto the base 1 and further ensuring the normal operation of the feeding work. When the board is placed above the drive roller 35, it is within the enclosure formed by the first baffle 7, the drop plate 6, and the two second baffles 23. When the distance between two adjacent drop plates 6 changes, the two adjacent worms 37 will also slide relative to each other. The worm 37 and the worm wheel 39 always remain engaged. Then, the motor 36 drives one side of the worm 37 to rotate, so that multiple worms 37 and worm wheels 39 rotate simultaneously. As a result, multiple drive rollers 35 rotate synchronously. Through friction, the board laid flat on the drive roller 35 is driven to move into the drop plate 6. After the board falls into the drop plate 6, the motor 41 drives the drop plate 6 to rotate. The board in the drop plate 6 will be tilted onto multiple drive rollers 35. This cycle is repeated many times, so that the orientation of the board laid flat on the drive roller 35 can be changed under the action of external force until the board can slide into the gap, thus further ensuring that the board can slide smoothly into the gap. However, in some cases, the surface of the board to be cut is relatively smooth. When the board comes into contact with the drive roller 35, it is difficult for the board to move laterally under the action of friction. As a result, the board laid flat on the drive roller 35 cannot move normally into the drop plate 6, which also affects the normal feeding of the board.Therefore, to avoid this situation, the push plate 12 also rotates during the rotation of the transmission roller 35. When the push plate 12 is in contact with the bottom of the board, the electric push rod 48 drives the push plate 12 to move, applying an upward oblique pushing force to the board, causing the board to move into the drop plate 6. After the push plate 12 completes one pushing action, it will retract into the inner cavity of the transmission roller 35, so as not to interfere with the board sliding into the gap. Thus, by continuously applying an upward oblique pushing force to the board, the board can slide smoothly into the drop plate 6, ensuring the normal tilting of the board by the drop plate 6. Moreover, compared with the method of applying a lateral pushing force to push all the boards laid flat on the transmission roller 35 into the drop plate 6 at once, this method will not cause the board entering the gap to be subjected to external force, avoiding motion interference and damage to the board due to compression.
